A Brief Introduction of Feature Matching

This paper presents several useful techniques about feature matching. As we know, for virtual worlds 3D reconstruction, we need many good 2D images with more precious correspondent matching points, thus, more realistic 3D models could be reconstructed for computer vision use, medical use or many other vision applications. This paper describes basis of feature matching, and also several further technical methods to achieve better correspondence matching. Experiment results show basic matching methods and different enhanced methods respectively, from which we can get ideas about how to make feature matching better.
